Which of the autoescape and safe filter tags is better to use?

I was looking for a way to unescape HTML in variables written in a Django template, and I found the answer here . So basically there are two ways to do this:

• Set autoescapeto off:

  {% autoescape off %}{{ myHTMLstring }}{% endautoescape %}
  

• Filter Usage safe:

  {{ myHTMLstring | safe }}
  

My question is which one is more appropriate for use (and in which context). I feel the filter safeis specific to Django, unlike autoescape, which seems to be also used in Jinja2. But what is your own way of thinking?
